Message Security over Image Communication

Previous work of us was to generate a secure Steganographic System with a password authentication, which is good enough for the host machine. But when the Steganographed image is communicated over the channel the security is quite low and interpretation of Steganography and the message is quite possible.In this paper an authentication system for Steganographed image is proposed in which a authentication watermark is used for the Steganographed image while being transmitted over the communication channel. They key distribution for the secure communication is generated using Kerberos.
